## Population Standard Deviation. If a data set represents the entire population, the true standard deviation can be calculated as follows: where r i is the ith value of the rate of return on an asset in a data set, ERR is the expected rate of return or the true mean, and N is the size of a population. Sample Standard Deviation

Stock A over the past 20 years had an average return of 10 percent, with a standard deviation of 20 percentage points (pp) and Stock B, over the same period, had average returns of 12 percent but a higher standard deviation of 30 pp. On the basis of risk and return, an investor may decide that Stock A is the safer choice, because Stock B's additional two percentage points of return is not worth the additional 10 pp standard deviation (greater risk or uncertainty of the expected return). Assuming that stability of returns is most important for Raman while making this investment and keeping other factors as constant we can easily see that both funds are having an average rate of return of 12%,however Fund A has a Standard Deviation of 8 which means its average return can vary between 4% to 20% (by adding and subtracting 8 from average return).
